Sharing a Note

Part of the Users and Accounts section of Coddy's Django journey. Lesson 15 of 16.

Notes are private, and that is right for most of them. Sometimes you want to show one to a friend: a recipe, a reading list. Over this lesson and the next you add read-only sharing.

Sharing starts as a choice the owner makes, stored on the note: a BooleanField, true or false. A new note must stay private unless the owner says otherwise, so its default is False. In a ModelForm a BooleanField becomes a checkbox.

Here the form may set the field, because it is the owner's choice about their own note. owner is different: no form may set it.

Challenge

Easy

Add a shared field to Note: a BooleanField that is False for a new note.
The owner can tick it in the note form when writing or editing.
A shared note's page shows Anyone with the link can read this note.

Press Run, log in as ada (password coddy-pass-123), edit a note and tick shared.

Try it yourself

from django.conf import settings
from django.db import models


class Note(models.Model):
    owner = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.CASCADE, related_name="notes")
    title = models.CharField(max_length=100)
    body = models.TextField(blank=True)
    created = models.DateTimeField(auto_now_add=True)

    class Meta:
        ordering = ["-created"]

    def __str__(self):
        return self.title
